The subject matter constituting the present invention relates to thefeeding mechanism of a candy wrapping machine and includes a feedingtable, its operating mechanism, a travelling belt and its associationwith said table, and mechanism for correctly seating the articles (inthe present instance caramels) for wrapping, on the belt.

Other and further important objects of this invention will be apparentfrom the disclosures in the drawings and specification.

The invention (in, a preferred form) is illustrated in the drawings andhereinafter more fully described,

f Description.

The caramel feed table is denoted as a whole by the reference number 1,and is provided with a raised border or enclosing wall 2, on three sidesthereof, which is of rounded contour on its inner and upper surfaces.Mounted on the feed table l, ad-

jacent the other side or edge thereof is a long plate 3, having adownwardly beveled edge, and beneath said plate isy a slidable,bevel-edged plate 4. Said plate 3, vis provided with guide slots 5, ateach end'thereof, engaged by guide pins 6, secured in the under plate 4,andclamping bolts 7, engage through said slots 5, and into the plate 4,to hold said plate 4 invarious adjusted positions. c, n i

Disposed below the beveled edge of said plate 4, is a grooved guidemember 8, over which the upper run of a feed belt 9 is adapted totravel, whereby the caramel may be fed onto the feed belt from thetable, and carried toward wrapping position. Said belt 9, is providedwith a series of pockets each adapted to receive a caramel and said`pockets are formed by partition members 10, secured to the belt in anysuitable7V manner, and each of said partition members 10, provided witha downwardly extending tooth 1 1, for engagement in said grooved guide8. A bracket 12, is secured. on the under side, at one end of said feedtable. ln the lower end thereof is a crank 13, which extends upwardlyand has secured therein a shaft 15, and journalled thereon is aperipherally groo-ved sheave or pulley 16.` Seated within a coredextension 17 of the bracket 12, as shown in Figures 4 and 6, is a coiledcompression spring 18, whichvbears outwardly against the upright crankor lever 13, operating normally to force said pulley 16 longitudinallyof said table, to provide a tension on the feed belt 9, which is trainedtherearound. A stud 19, is secured in a boss extension 14 and securedthereon is an upright 20, shown in Figures 2, 3, 4 and 6. Secured tosaid upright 20, is a long bar 21k which near its other end is securedto an upright 22 and extends therebeyond, and is attached to thewrapping machine. Said bar 2l is adjacent to and at one side of theupper run of the feed belt 9, and operates to confine the caramels andassist in squaring the same into position on the belt as they are fedthereto from the table l. Another confining bar 23, is attached to oneend of the table '1, on one of the side walls 2, as shown in Figure l,and to the frame of the wrapping machine denoted by the referencenumeral 24, and together with that part of the bar 21 beyond the upright22, prevents displacement of the caramels from the feed belt as they areoperated upon, if not in proper position, by a stripper or truingmechanism. This comprises a candy righting element 25, which is securedby screws 26, extending through the beveled slidable plate 1l, and saidrighting element projects outwardly through a slot 27 provided thereforin the beveled plate t. Said righting element by reason of itsconnection to the slidable plate 4t may be adjusted into various angularpositions over the feed belt 9, shown in Figure 8, ,fitting closely overthe partitions l0 thereof. Journalled in suitable bearings provided forthe purpose on the wrapping machine is a groove-d driving pulley 28,having notches therein for engagement with the inwardly projectingtongue portions 11 of the belt and around which said feed belt 9 istrained,

as shown in Figures l and 2. Secured upon the same shaft with saidpulley 28, to drive the same is a sprocket wheel 29, driven by a chainfrom any suitable source of intermittent drive.

The caramels to be wrapped are placed upon the table l and then movedmanually by a pusher bar or by tilting of the table l to cause t-he sameto fall towards the intermittently travelling feed belt 9. Each space onthe feed belt, between the partitions 10, is adapted to receive a singlecaramel. therein and the confining bar 21 along one side of the beltserves to assist in squaring the caramels into position upon the belt..bis the oaramels are carried along by said belt 9, if they are notproperly square-d into true position on said belt, they will becontacted by the righting element 25, extending over the partitionmembers l0 on the belt. ril`hus any caramels which Ina-y be in squaredposition on the belt with reference to the confining bar 21, if notsquared otherwise, that is if tilted upwardly, will be contacted by thevrighting element 25, which owing to its long gradual inclined relationto the path of travel of the belt, will necessarily cause the caramelsto readjust their positions on the belt to the proper squared relationtherewith. After passing .by the righting element 25, the belt travelsinto the field of operation of ejecting devices which feed the caramelsfrom vthe belt to the wrapping mechanisms which,

however, form no part of the present invention.

The bar or plate 4:, is adjustable into close relation with thepartition members 10 of the belt 9, so that. the caramels sliding downthe beveled edge of plate fl fall directly into a pocket on the feedbelt 9. The pulley 16, around which one end of the belt- 9 is trained,is spring impelled by the spring 18, operating against the pivoted lever13, so that the proper tension upon the feed belt is maintained at alltimes.

l am aware that numerous details of construction may be varied through awire range without departing from the principles of this invention, andl therefore do not purpose limiting the patent granted otherwise thannecessitated by the prior art.

l. in a candy wrapping machine, a feed table having an inclined edge, acaramel conveying element passing along said inclined edge and adaptedfor receiving caramels fed down said inclined edge,-and a rightingelement adapted for righting any improperly positioned caramels on saidconveying element.

2. In a candyv wrapping machine, a conveying element having pocketsadapted for receiving candy, and a candy righting element co-operatingtherewith to right improperly positioned candy thereon.

3. In a candy wrapping machine, an adjustable inclined element, a candyconveyor passing adjacent said element and adapted to receive candy feddown said inclined element, and a candy righting element secured to saidadjustable element for righting the candy on said conveyor.y

ft. In a candy wrapping machine, a. travelling belt conveyor, mechanismto discharge carainels thereon 'in inclined positions, and a rightingelement `for moving tilted caramels into upright positions.

In testimony whereof l have hereunto subscribed my naine in the presenceof two subscribing witnesses.
